UNITED STATES PATENT OFFIGE.

GEORGE G. SCHELTER, OF ROCHESTER, NEW YORK.

LAST.

To (LZZ whom it may concem:

Be it known that I, GEORGE G. SCHELTER, a citizen o'l' the United States, and resident oi' Rochester, in the county of Monroe and State oi' New York, have invented new and useful Improvements in Lasts, o'l' which the following is a speoification.

This invention relates to improvements in lasts and more partioularly to lasts which are divided transversely by lines of cut which l'orm an Opening or recess extending into the body oi' the last from the top and in which the two parts of the last are bonded together by two bonding plates extending aoross the line o'l' division and anchored one end in the i'ore part and the other end in the heel part o'l' the last.

I have shown my invention as embodied in a last similar to that shown in a patent to Amos G. Fitz, filed April 17, 1906, Number 817 ,966, but the same is not limited thereto being oapable of use in any divided last where one part is movable relative to the other.

In the drawings herewith aooompanying and making part of this application, Figure 1 is a longitudinal vertioal seotional view el' the last Showing one embodiment of my invention applied thereto; Figs. 2, 3, 4 and 5 are longitudinal vertioal sectional views ol' parts oi' lasts Showing different embodiments oi' my invention.

Same letters o'f reference refer to like parts.

In said drawings A represents the i'ore part and B the heel part of a last, C the line of division and D and E the bonding plates. The bonding plates are vertioally mounted one above the other in keri's F and G in the i'ore and heel parts respeotivel and are of a thiokness substantially to *'t the kerfs. It will be noted that in all the varying i'orms shown the looking device is so oonstruoted as to look one bonding plate to the other as distinguished from my com anion application oi' even date herewith w erein the looking deyioe is connected with one bonding plate on y.

Lasts designed for lasting purposes must neoessarily be Strong and oapable of resisting great strains and pressures and when divided require means for positively lookin the two parts in extended position. It is a so neoes sary that the looking device be capable oi" rapid manipulation and oi' operating with absolute oertainty to make a perfect look and my invention is speoially designed to accom- Speoifioation of Letters Patent.

Applioation filed December 6, 1907.

Patented Dec. 15, 1908.

Serial No. 405,323.

plish all of these purposes in a divided last. Kerfs in the divided last l'or the reception o'l' the bonding plates are absolutely neoessary. I have utilized the kerl's and bonding plate l'or the reception of the looking device, .the looking device being positioned so that it can be manually operated, it extending into or across the open space or recess between the two parts ol' the last.

In Fig. 1 I have shown the two plates locked together by means ol' a Spring looking bar H seoured to one end ol' the plate E and having its 'free end in locked engagement with the under side ol' plate D. It is adapted to be manually disengaged by a l'orked lever rotatably or pivotally mounted upon the end 01' plate D, one arm l in engagement with the looking bar II and the other arm J extending across the Opening or recess Z in the last, downward pressure upon arm J oausing arm I to disengage the looking bar H.

In Fig. 2 the looking device consists of a rigid looking bar K pivotally mounted in the end of plate E and its free end in locked engagement with the opposite end o'l' plate D. A spring L tends constantly to hold bar H in locked engagement with plate D. T he looking bar K is manually unlooked by downward pressure on arm J oi' a forkod lever pivotally mounted on plate D causing arm I to disengage the looking bar.

In Fig. 3 the looking device consists of a spring looking bar M, one end secured to the plate E and the free end in looking engagement with the plate D. The looking bar M tends constantly to press upwardly into locking engagement with the bar D and is manually unlooked by means ol" a plate N pivotally mounted in the heel part and extending forwardly into the fore part in the kerfs in the fore and heel part rospeotively and by the side of the plate D. The under edge of plate N is provided with a lug 0 extending laterally in the path of' looking bar M and the upper edge for oonvenience with a finger piece P. Downward pressure exerted upon plate N causes lug O to force looking bar M out of engagement with plate D.

In Fig. 4 I have shown the looking device pivotally connected with plate D and provided with one arm Q adapted to have looking engagement with the plate E and the other extending across the recess or open space in the last. A Spring R tends constantly to press arm Q downwardly into looking engagement with plate E. In this oase the parts are manually unlooked by upward pressure on arm S of the looking bar.

In Fig. 5 I have shown the two bonding plates D and E looked together by means of a vertioally moving bolt T, whioh passes through plate D and into looking engagement with plate E. The bolt is held in position by means of a pivoted lever V one end W engaging the looking bolt and the other end in engagement with a spring X, tending oonstantly to keep the bolt in looked position. It is manually unloeked by downward pressure on the end of the looking lever Which lifts the looking bolt out of engagement with plate E.

I have shown some of the many forms in whioh my invention may be embodied but do not wish to be limited thereto as any means for looking the two parts of divided lasts bonded together by two bonding plates one positioned above the-other which looks said bonding plates together is within the Spirit and soope of my invention.

Having thus desoribed my invention and its use I olaim:

1. In a two part divided last having a reoess eXtending into it from the top, kerfs in the adjaoent ends and two bonding plates one above the other, eaoh having one end pivotally mounted in the fore part and the other part pivotally mounted in the heel part, means for looking said bonding plates together to prevent movement of' one part of the last relative to the other.

2. In a two part divided last having a reoess eXtending into it from the top, kerfs in the adjaoent ends and two bonding plates pivotally mounted in said kerfs one above the other, a looking bar having one end seoured to one plate and the other end in looking engagement with the other plate and ieans for manually disengaging said looking 3. In a two part divided last having an Opening extending into it from the top, kerfs in the adjaoentends and two bonding plates pivotally mounted in said kerfs, a looking bar attaohed to one plate and adapted to have looking engagement with the other part, a spring tending oonstantly to hold said looking bar in engagement with said plate and fiieans for manually disengaging said looking In testimony whereof, I have signed my name to this speoifioation in presenoe of two subsoribing witnesses, this 4th day of November, 1907.
